Timing and Stability Analysis of Carbon Nanotube Interconnects

This paper deals with timing and stability analysis of single wall carbon nanotube (SWCNT) bundle and multiwall carbon nanotube (MWCNT) interconnects. The performance of SWCNT and MWCNT interconnects are analyzed using driver-interconnect-load system. It is analyzed that MWCNT interconnects are more stable than SWCNT bundle interconnects. It is illustrated that stability of both SWCNT bundle and MWCNT interconnects increases as the length of interconnects increase. The analytical model for stability and step response using ABCD matrix have been presented. The results are verified using SPICE simulations. The average error between analytical and simulation results is 2.1%.
